All Ballheads are made to exacting standards. Each component is milled from a solid block of aluminum and computer-machined to tolerances within a thousandth of a centimeter. Parts are then polished, finished and hand assembled. Plated steel threaded tripod sockets and camera mounting screws are fitted, knobs are installed, and non-slip surfaces are applied to the camera platform. Finally, each ballhead is tested for smooth movement and lockdown strength.
